Overview of virtual health data tables

The data landscape for healthcare can be complex and expensive, which creates challenges for customers and partners looking to develop healthcare solutions. Dataverse offers a powerful solution for building low-code, no-code healthcare applications. But, its underlying data storage sometimes can't be the best choice for achieving enterprise interoperability.

Virtual health data tables in Microsoft Cloud for Healthcare provide an option for achieving this interoperability. Dataverse includes the Virtual tables feature that enables surfacing records within Dataverse from external sources. Virtual health data tables extend this feature via a custom virtual table provider for FHIR-based data. This custom provider includes capabilities that allow you to dynamically switch the data source between Fast Healthcare Interoperability Resources (FHIR) endpoints and Dataverse via Data routes. For example, you can configure your solution to access Encounter data persisted on Azure Health Data Services while maintaining Allergy information in Dataverse.

Virtual health data tables can help you build low-code/no-code solutions that extend beyond common Dataverse boundaries, while users continue to interact with the virtual data as if it were regular Dataverse record. They allow you to be selective about data storage and reduce the complexity of dealing with FHIR data interchange. This solution also uses the existing entity and attribute maps used by the Dataverse healthcare APIs. It supports Application Lifecycle Management (ALM) through solution deployment and reduces the cost of ownership for system administrators.

Data routes

Virtual health data tables take the best of the Dataverse virtual tables (entities) solution and layer it on top of a data routing concept.

A diagram displaying the data routing concept.

A key limitation with Dataverse virtual tables is the lack of tools to convert an existing physical table to a virtual one and vice versa, which leads to the creation of new tables. If you need to switch to either virtual or physical, you must reconfigure your Dataverse applications to use the new table structure. Furthermore, you might have to preserve both virtual and physical tables to accommodate complex interoperability requirements. If your design approach includes both virtual and physical tables, you encounter two possible tables to use when creating saved views and advanced finds.

Virtual health data tables solve these challenges by allowing you to establish data routes for your tables or entities.

Note

Unsure about Entity versus Table? Go to Developers: Understand terminology in Microsoft Dataverse.

Standard Dataverse virtual tables require static mapping to the remote schema and a single data source at runtime. Data routes in virtual health data tables provide a configurable option to route requests on virtual tables to either the physical Dataverse store or to the remote FHIR endpoint. This option provides the flexibility to start with your data in Dataverse and enable connectivity to a FHIR endpoint later.

Each virtualized FHIR resource has its own data route configuration entry, so you can also route requests independently. For example, you can enable Encounters as virtual while configuring Allergy Sensitivity to Dataverse. You can change this configuration anytime and the custom provider immediately redirects from where the data is accessed.

Note

While the configuration changes are immediate, you're responsible for any data cleanup or move. For example, if Encounter is changed from Dataverse to virtual, the encounter records aren't automatically deleted from Dataverse.

As you virtualize more FHIR resources and their virtual Dataverse tables, each new entry also inherits this data route capability. For more information on how to configure the data routes, go to Configure virtual health data tables.

Entity and attribute maps

Virtual health data tables use the same entity maps and attribute maps used by the Dataverse healthcare APIs. You only need to map your FHIR data elements once and can rely on consistency when FHIR messages are processed.

For more information, go to Entity maps and Attribute maps.

Supported features

The following section lists the features supported by the virtual health data tables:

  • Create, update, and delete operations: Create, Update, and Delete operations are available on both root level and expansion resource records. You can perform these operations using the standard Dataverse forms for the virtual health data tables.

    Similar to standard virtual tables, security roles determine which operation is permitted. You can restrict the create, update, or delete operations on one or more tables. Also, you need attribute maps with the FHIR Required Attribute field when you save the record to ensure conformance with the HL7 FHIR specification.

  • Expand: The feature supports expand tables for each available virtualized table.

    • Retrieve multiple query: When expand tables are configured to route data from a virtual data provider, the retrieve multiple query is supported only if the query contains filters on the parent link attribute. For example, Observation Component is an expand entity of the Observation entity. The entity map for Observation Component is configured as shown in the following screenshot:

      A screenshot showing the observation component configuration.

      The retrieve multiple query for the observation component must contain a filter on specific IDs of the parent link attribute msemr_observation.

      A screenshot displaying sample filters for the observation component.

    • Retrieve: Because the expand entries don't have a unique ID in FHIR, we don't support retrieving expand entries using an ID. The ID that appears when you select a record from a set of retrieve multiple results is temporary.

  • Filtering: The feature supports column filtering as defined by the HL7 FHIR specification. You can filter on linked entities for only one level.

  • Composite filtering: The feature supports limited composite filters for single table composite filters. For more information about composite filters, go to Composite Search Parameters in the HL7 FHIR documentation.

    The feature supports the following composite filter definitions:

    Composite filter Description
    code-value-concept Code and coded value parameter pair
    code-value-date Code and date/time value parameter pair
    code-value-quantity Code and quantity value parameter pair
    code-value-string Code and string value parameter pair
    combo-code-value-concept Code and coded value parameter pair, including in components
    combo-code-value-quantity Code and quantity value parameter pair, including in components
  • Linked entities: The feature supports linked entities filters using chained filtering as defined by the HL7 FHIR specification. The level of support depends on the Azure API for FHIR version. Unsupported filter conditions surface exceptions, and return no results.

  • Sorting: Sorting is implemented as defined by the HL7 FHIR specification. The level of support depends on the Azure API for FHIR version. Unsupported sorting conditions still return data.

  • Notifications and exceptions: Notifications are provided in context of virtual health data tables when configured as virtual. You receive a notification that the virtual records are available with limited sorting, and filtering is based on the Azure API for FHIR version.

Things to remember

The following section lists key implementation considerations to remember if you plan to enable the virtual health data tables feature. However, this list isn't exhaustive.

For more information, go to Limitations of virtual tables.

Risk User experience Potential mitigation tactics
Virtual tables don't support existing saved views and dashboards All the charts and dashboards created using physical entities that are later virtualized would no longer function. Refactor saved views and dashboards to use the new virtualized entity.

Note the new Native text added to the front of the legacy Dataverse versions of the virtual health data tables.
The virtual versions of these tables are, for example, named Encounters or Observations.

Communicate changes to users. Along with system views, you also need to refactor personal views.
Virtual tables don't support standard charts The charts don't function or aren't available for creation. You need Power BI or an alternative solution for visualizing this data. Model-driven charts don't render for virtualized data.

Communicate changes to users. You can no longer have charts in personal views and dashboards if you created them before using physical entities.
Relevance search isn't supported Relevance search doesn't function for virtual health data tables. Communicate changes to users. Assess if you can use virtual entities in your deployment.

The new default search experience in model-driven Power Apps is built upon relevance search.
AI Builder isn't supported Any AI Builder insights that previously used physical Dataverse tables would no longer be available when you virtualize those tables. Consider other Microsoft AI options.

The data sets you're considering virtualizing in Dataverse should likely be analyzed with Azure services such as Azure Synapse Analytics to uncover opportunities in your business.
Virtual tables feature a simplified security model as only organization-level security is currently supported. Examine the security for compliance requirements. If organization-wide security on FHIR based resources isn't a fit for your deployment, reconsider enabling the virtual health data tables feature.

Known limitations

Because the virtual health data tables feature is based on Dataverse's existing virtual table solution, it has the same limitations as the virtual tables. Consider these limitations when you determine whether this feature works for your needs.

The following limitations also apply to virtual health data tables:

  • The feature currently only supports connecting to Azure FHIR services, Azure API for FHIR, and Azure Health Data Services. Configurations for these versions deploy as part of the baseline solution. For more information, go to What is FHIR service?

  • Support for search and sort depends on the version of the configured FHIR server. For more information, go to Overview of FHIR search.

  • For search and filtering, the feature only supports a single level of link entity.

  • For search and filtering, the feature only supports a single level of expand entities.

  • For virtual tables, relationships to non FHIR-based tables aren't supported.

  • Creating and deploying your own virtualized tables isn't currently supported.

Virtual health data table events

Dataverse virtual tables include the ability to register for asynchronous events from an external data source. Virtual health data tables in Microsoft Cloud for Healthcare extend this feature to raise events for activities performed on remote FHIR endpoints using the existing Dataverse healthcare APIs infrastructure. For example, if you create an Encounter on the FHIR server, it raises an event in Dataverse in the context of the virtual table msemr_ve_encounter. You can then register your plug-ins for create, update, or delete events raised on virtual encounters.

The virtual health data tables feature allows dynamic switching between Dataverse and virtual providers through data routes. Hence, it also raises these inbound events if you configure your data route value as Dataverse. In the previous example, this behavior means that you only need to register the plug-ins once against msemr_ve_encounter. Even if the data route changes between Virtual and Dataverse, it still invokes your plug-in.

This event capability allows you to register plug-ins against events to execute custom workflows for data not persisting in Dataverse.

The following tables support virtual table events:

  • Allergy/Sensitivity (msemr_ve_allergyintolerance)
  • Encounter (msemr_ve_encounter)
  • Episode of Care (msemr_ve_episodeofcare)
  • Observation (msemr_ve_observation)

For more information on virtual table events and examples, see Enable Virtual Tables to support Dataverse events.

Prerequisites for virtual health data table events

The virtual health data table events feature is built on both the existing virtual health data table functionality and the Dataverse healthcare API functionality. Besides the prerequisites for virtual health data tables, the following prerequisites also apply to the events feature:

  • You need to configure the Dataverse healthcare APIs as they provide the entry point for virtual health data table events. The APIs process the messages that trigger events for virtual tables from the FHIR server. For more information, see Overview of Dataverse healthcare APIs.

  • Tables that participate in virtual events on the remote FHIR server should have their data route configuration values set to Virtual. Otherwise, the data would be ingested into Dataverse as part of the standard Dataverse healthcare API message processing.

  • Bundles posted to the FHIR server should include the HTTP method value request.method for each resource entry. For more information on this FHIR entry node, see Bundle resource element - Bundle.entry.request

For examples on how to register your own plug-ins for virtual health data table events, go to Use virtual health data table events.

Things to remember for virtual health data table events

  • Virtual table events are asynchronous.
  • Events only trigger on virtual tables mapped to root-level FHIR resources, and not on expansion tables.
  • For data routes set to Dataverse, events only trigger for entity maps that aren't disabled.
  • Attribute maps determine what values are provided in the entity available via the plug-in execution target object. If an attribute map isn't available for a FHIR resource node value, the field value isn't processed and available in the event payload.

Known limitations for virtual health data table events

The FHIR bundle for events currently only supports the HTTP method value request.method for PUT. All events sent during this phase are treated as virtual table externally created events, regardless of their actual type.
